Making the search a little easier... New battery from amazon is 900Mah Vs 700 oem. Should last longer. New battery is slightly larger and required cutting a plastic stop in the compartment with wire dikes that held the OEM in place. Easy peasy solder job once i went to Harbor Freight and bought some hobbie hands to hold the wires together while i held the gun and solder wire on the power wires. I used liquid electrical tape with a few coats to keep the wires flexible in the case vs heat shrink tubing I know some folks may use coms for training or just in casual rides. Thought this may be helpful since SENA says the battery in the com is unservicable
